Getting Started with gWLM

gWLM is typically accessed through HP SIM. For information on the gWLM command-line interface, see gwlm(1M).

After performing the necessary gWLM daemon (or service) configuration as described in the VSE Management Software Installation and Update Guide, the quickest way to start using gWLM to manage new systems is to use the Manage Systems and Workloads wizard, as described in the following text.

Before you start the wizard though, decide:

Which systems you want to manage with gWLM
Whether you want to manage your workloads by migrating CPU resources among npars, vpars, virtual machines, processor sets, or fss groups. (CPU resource migration among npars with spare capacity is simulated using the HP Instant Capacity product, as explained in the section “The gWLM Management Model”.)

Tabs and Menus

The controls shown in Figure 2-1 appear at the top of the Global Workload Manager screen.

Using the Wizard

To start the wizard:




	NOTE: You must be logged in as root on the systems where you run the mxstart, gwlmcmsd, and gwlmagent commands mentioned below. In HP SIM, you must be logged in as root or have authorizations for “All Tools” or “VSE All Tools.”

Configure your CMS as indicated in the VSE Management Software Installation and Update Guide if you have not already done so
On each managed node, start the gWLM agent if it is not already running:
# /opt/gwlm/bin/gwlmagent
Alternatively, you can start the agent through HP SIM, as discussed in the VSE Management Software Installation and Update Guide.
Connect to HP SIM by pointing your web browser to:
http://hostname:280
where hostname represents the hostname of the CMS.
Select:
ToolsVSE Management
and then click the Shared Resource Domain tab. From the VSE Management menu bar, select:
CreateShared Resource Domain

The wizard guides you through the following steps:

Specify the hosts on which to run workloads that you want gWLM to manage as part of one SRD.
Set SRD properties.
Properties include the SRD name, mode, use of Temporary Instant Capacity (if available on the system), and resource allocation interval.
Specify workload and policy settings.
Settings include the workload name and policy.
Review and confirm the SRD.
Verify the SRD is configured as expected, and click Finish to have gWLM manage the resource allocation for the workloads in the SRD.
